Abstract

The absorption and desorption process of SO2 by ionic liquid which is useful for the recycle of SO2 into sulfuric acid generation reaction after sulfuric acid decomposition in the thermochemical Sulfur-Iodine cycle was studied. Most of ionic liquids studied were applicable at high temperature desorption without volatility around 300°C except [BMIm]Cl, and [BMIm]OAc, which showed the decomposition of ionic liquids. By the FT-IR spectra, the physical absorption was verified with the fact that no spectra peak position change of ionic liquids before and after SO2 absorption except the generated SO2 peak in the spectrum. This is an abstract of a paper presented at the AIChE Spring National Meeting (Houston, TX 4/22-27/2007).
